T all 1li/10mz't may concern Be it known that I, FREDERICK C. OVER- BURY, a citizen of the United States, and a resident of Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Shingle-Stripspf which the following is a specification. i

This invention has relation to prepared' waterproof weatherproof coverings for roofs andside walls, which, when laid, present the appearance of shingles or tiles.

Prepared roofing usually consists of a sheet of felt or similar fibrous material impregnated or saturated with some waterproofing composition, and having on one or both faces a layer of pitch, asphalt, or the like, in which is frequently embedded crushed mineralc'material. In such sheets,

.20 the fibers composing the felt in the main eX- tend generally longitudinally of the sheet,

and, when the roof covering is exposed to the action of the elements, it tends to expand and contract crosswise of the sheetor of the general direction of the fibers.

I have found that, by'cutting the sheet crosswise into strips and forming the shingle-like or tile-like projections thereon, to extend in the general direction of the fibers,

I am able to prevent any material bending or buckling of the strips and the tabs thereof when laid.

Hence the present invention consists, as a new article of manufacture, of ashingle V strip formed of waterproof roofing felt having along its lower edge spaced tabs or `projections of any suitable configuration which extend longitudinally of the fibers of the felt Thesestrips, when laid in overlapping "10 rows to expose said tabs or projections, present the appearance of a shingle or tile roofing.

On the accompanying drawing,-Figure l illustrates a sheet of prepared fibrous material and shows how the shingle strips may be formed therefrom. Fig. 2 illustrates one 'of the shingle strips. Fig. 3 shows a shingle strip having different shaped tabs. Fig.

4. represents a section 5.0' Fig. 2 on a larger scale.

In the manufacture of wool felt, such as I employ for the foundation of my roof covering, the fibers are in the main arranged longitudinally of the length of the strip or sheet, and, in accordance with the present on the line 1 -4 of invention, the shingle strips are cut from the sheet along lines transverse to the longitudinal lines of the sheet so that each strip, although it is provided with a. plurality of tabs or projections which when laid form the appearance of tiles or shingles, are relatively short, and, because of the arrangement of the fibers transversely of the length thereof, do not bend and buckle when exposed to varying thermal and weather conditions. The foundation of the strip consists of such wool felt which is saturated or impregnated with the usual waterproofing composition employed in the manufacture of prepared weatherproof roofing, such as pitch, asphalt and the like. The sheet of felt, after being impregnated and saturated with waterproofing compound, is then coated on one or both faces with a weatherproofing coating such as asphalt or pitch of such consistency that it will not runwhen exposed to solar heat. In some cases, the coating on the outer face of the sheet has embedded therein any suitable mineral material, such as ground or crushed slate or, granite or sand, the embedment occurring while the coating is in a soft and plastic state.

In Fig. 4, the impregnated felt is" indicated at a, the coatings of weatherproof mal lacross the sheet as shown in Fig. l. What may be termed the rear ends of the slits are connected by a cross-slit la., so that there are formed a series f rearwardly extending tongues c' which are connected at their front ends to the main body of the sheet. These rows of tongues are separated, longitudinally of the sheet, by a distance of say 7 to 10 inches more or less as circumstances may require. Then, by any suitable cutting tool or other instrumentality, the sheet isr severed on the dotted line j, j in Fig. 1, the said line coinciding with the forward ends of the `slits g. As a result( of this procedure, there is ll@ loo formed a series of shingle stripsl c,'eaclr of which is formed at its front or lower edge with a series of tabs or projections m separated by slots n, with a straight edge o defining its upper or rear end. Any other method, however, may be followed in orming the strips from the sheet to secure the desired` formation of tabs or projec ions. these strips, the fibers of the impregnated felt extend mainly in lines approximately parallel to the end edges p, p of the strips,

so that, when the strips are laid in parallel for example:

overlapping rows, the tendency to buckle and bend is practically elilninated. In ,laying the shingle strips upon the roof, each row of strips isv overlapped by the succeeding higher rgw with the shingle tabs or projections m of one row either coinciding with or bridging the upper ends of the slots n of the next lower row.

It is quite-apparent, from the foregoing,

descri ition, that, by the employment of any suitable cutting instrumentalities, the lslits or incisions which are formed in the sheet may be of diverse character, so that the tabs, instead of being substantially rectangular, may be'of other shapes," as shown in Fig. 3 It will be understood, of course, that the elongated sheet will be fed forwardly longitudinally of its length, so that, the shingle lstrips will be cut successively from the end ofthesheet.

Inaddition to the advantage secured by l preventing) the bulging Aof the strips after they have een laid, the strips herein possess other advantages which those skilled in the art will recognize and appreciate. For ex-"" ample, they may be quickly and cheaply manufactured in any predetermined lengths according to the width of the sheet .from 40 In which they -are cut and with any limited number of spaced tabs of suitable configuration, and they maybe laidon the 'roof structure easily and with a minimum number of fastenings.

Having thus explained the nature of my said invention and described a Way of making and 'using the same, although without setting forth all ot th forms in which it may be made or all of the modes of its use, r

FREDERICK C. OVERBURY.
